Actually the main question you have already answered. Does the breaking and recreating fix my replication issue? And your answer was NO. That is the same what I thought. Now that this is confirmed I do not have to waste my time on trying that....
However as I said I still have a problem. What I meant with was the following:
In the replication settings i have configured "Custom" that I am able to select items individually. For example I have enabled the folder with all my Managed Software Delivery policies for replication. Once enabled they should be replicated with the "differential" and "full" replication schedule. However it seems like since upgrading from 7.1 to 7.5 this has stopped working. This is the main problem.
When I was suggested the "solution" with breaking and recreating the hierarchy I was thinking I need to know which items are enabled for replication to be able to reconfigure the items in case this information gets lost during the recreation of hierarchy. Therefore I thought the report "Review the current Item replication report" is the one to look at but this is the one which always comes back empty. Not even an error is show in the web console. However there is the error mentioned above in the SMP logs... So I thought that is maybe a starting point....
"Replicate Now" and "Standalone replication" seems to be functioning normal.
